SPECIFICATION' forming part of Letters Patent N0. 788,102, dated April 25, 1905.

Application filed December 2l, 1904. Serial No. 237,760.

Be it known that I, CHESTER E. HENING, of North Baltimore, county of IVood, and State of Ohio, have invented certain newand useful Improvements in Rain-Tater Filters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being' had to the accompanyingdrawings, and to the figures of reference marked thereon, which form part of this specification.

rlhis invention has reference to a rain-water filter; and it has for its object to provide an improved device of this character for effectively removing' the usual foreig'n material-- leaves, twigs. insects, soot, &c.carried by water from the roof of a building' into the cistern.

A further object consists in arrang'ing the parts within the filter-casing so that they may be readily removed therefrom for the purpose of cleaning'.

In carrying' out myinvention I employ the novel combination and the arrangement of the parts hereinafter shown, described, and claimed.

In the accompanying' drawings, Figure l is a view showing my filter. Fig. 2 is a transverse section thereof, illustrating' its operation. Figs. 3 and l, respectively, are perspective views of the filter parts removed from the casing'.

Referring to the drawings, l is a sheetmetal casing of rectangular shape adapted to be secured in any suitable manner to the side of a building, the same being provided with a removable cover 2, the inlet for water from the roof being indicated at 3 and the outlet or discharge to the cistern at et.

5 is a sheet-metal slide or partition removably secured in the casing, the same extending crosswise in a vertical plane between the front and rear walls thereof, the casing being' divided thereby into two chambers 6 and T, passage from the chamber 6 into the chamber T being effected through a plurality of transversely-arranged perforations 8 near the upper end of the partition. The partition is guided upon insertion and removal between fianged pieces 9, secured one to the front and the other to the rear wall of the casing'.

l0 is a pocket carried by the partition 5, adapted to contain pieces of sponge or like liltering' material, (indicated at ll,) one side of the pocket being formed by the perforated portion of the partition, the other side, l2, being a section of wire screen soldered at its upper and lower margin to the partition.

13 is a basket, of reticulated material, the same having a rectangular shape to completely occupy the lower end of the chamber 7. This basket is also permanently carried by the slide 5, being removed from the casing when the slide is removed therefrom. \Vithin the basket 13 is placed a quantity of loose charcoal, the same serving as a filtering and purifying' agent for the water.

le indicates an elongated rectangular screen having a suitable marginal frame l5, of metal, imparting stiffness and rigidity thereto. At its lower end the screen is turned upwardly, as at 16, providinga pocket for the reception of foreign materialA deflected into the same from the face of the screen. As shown in Fig. '2, the screen li is inclined steeply within the chamber 6, with its upper margin resting' upon the slide 5, the same being' capable of ready removal from the casing when desired.

1T is a cock at the bottom of the chamber 6, adapted to drain any accumulated sediment therefrom.

The operation of the filter isas follows: The water entering' the filter-casing' at 3 is discharged directly into the water contained in the chamber 6, the force of the discharge being broken before it reaches the screen 14, which, itis observed, is submerged in the chamber 6. It is apparent that if the screen l-L were not submerg'ed the usual foreign material contained in rain-water-deeayed leaves, twigs, insects, &c.--would be 'forcibly directed against the same, the force of the impact, aided by the action of the water, reducing the foreign material to extremely line particles capable of readily passing through the screen. The disintegration of the foreign material is entirely prevented by the arrangement of screen shown. The Vforeign material after IOO being discharged into the water within the chamber 6 is carried without undue violence against the inclinedscreen, being then deiiected into the pocket at the lowerl end of the screen out of the path of the current. (Indicated by the arrows, Fig. 2.) The coarser foreign material having been removed from the water there still remains therein the finer material, such as soot and dirt, held in mechanical suspension. This finer material is removed by the Sponges contained in the pocket carried by the slide, the water passing through the perforations in the slide. The charcoal in the basket at the lower end of the chamber 7 accomplishes the final removal of all foreign material, the water being discharged into a cistern o r other suitable receptacle.

One of the features of my invention lies in the facility with which it may be cleaned. Since the coarser foreign material is deposited in the pocket at the lower end of the screen 14, the same is readily removed from the casing by lifting the screen out of the chamber 6. Any sediment or deposit of fine material at the bottom of the chamber 6 may be readily discharged by opening' the cock 17. The

'removal of the slide 5 carries with it the sponge-pocket and also the receptacle for charcoal, these parts being cleaned by thorough drenching with water. It will be observed that when the screen and the slide are removed from the casing the latter is simply a rectangular box-like structure, the water being free to pass therethrough without obstruction. This is desirable in winter, the parts being removed to prevent their freezing when the weather conditions would indicate a sudden drop in the temperature.

The improved operation of my invention will be apparent.

Having described my invention, what I claim, and desire to secure by Letters Patent,

l. A rain-water filter comprising a casing, a partition dividing the casing into-two chambers and provided with passages for Water, a

structure containing a filtering medium disposed in one of the chambers, an inclined screen submerged in the other chamber, an upturned portion forming a pocket at the lower end of said screen, a water-inlet at the top of the chamber containing the submerged screen, and an outlet at the bottom of the other chamber, substantially as described.

2. A rain-water filter comprising a casing, a removable partition provided with passages for water through its upper portion, said partition dividing the casing into two chambers, an inlet for water at the top of one of the chambers, an outlet at the bottom of the other chamber, an inclined screen submerged in the chamber having the water-inlet and removably seated in said chamber, said screen havl ing an upturned lower portion, and a reticulated structure containing filtering material carried by the removable partition and disposed within the chamber provided with the water-outlet, substantially as described.

3. In a rain-water filter, a casing, a partition dividing the casing into two chambers, slidably secured between its front and rear walls, said partition having passages through its upper portion, a pocket containing filtering material arranged in front of said passages, a reticulated basket containing filtering material carried by said partition and occupying the lower portion of the chamber on one side of the partition, an inclined screen provided with an upturned lower portion submerged in the chamber on the other side of said partition, said screen being removably seated in said chamber, an inlet leading into the top of the chamber containing the inclined screen, and an outlet at the bottom of the other chamber below the reticulated basket, substantially as described.

In testimony that I claim the foregoing as my own Iaffix my signaturein presence of two witnesses.
